Review on Seachem 67106760 Reef Buffer 250Gram by Stephanie Bourque

This is total crap! I've been trying to keep the pH at 8.2 in my Fluval Evo 11 for a week now. This crap only raises the pH to 8.2 for a few hours and then drops back down to 7.4. Used reverse osmosis water and Red Sea salt as directed. Still no luck. Don't waste your money on this garbage. I kept a 150 gallon reef for 12 years in the 90's, I used a GH ph-up and always had 8.2 with a few drops and it stayed 3 weeks straight. :). Will be ordering another bottle once this review is done. Yes this is for hydroponics but it works GREAT on the reef and is safe. Just use an eyedropper.
